bio lab quiz 5

Question 1

which organisms perform cellular respiration

Answer 1

all living organisms

Question 2

what is ATP

Answer 2

adenosine triphosphate is the energy currency of living systems, made in the process of cellular respiration

Question 3

aerobic cellular respiration

Answer 3

oxygen is the substrate

Question 4

anaerobic cellular respiration

Answer 4

occurs in the absence of oxygen, like in bacteria and fungi

Question 5

basic steps of cellular respiration

Answer 5

1. breakdown of large macromolecules to simple subunits
2. breakdown of simple subunits to acetyl-Coa accompanied by production of limited ATP and NADH
3. complete oxidation of acetyl-Coa to H20 and CO2 involves production of much NADH, which yields much ATP via electron transport
   or (glycolysis and krebs cycle)

Question 6

Kreb’s cycle or citric acid cycle

Answer 6

complex series of metabolic reactions occurring in the matrix of a mitochondria

Question 7

what are the waste products of photosynthesis

Answer 7

sugar and oxygen

Question 8

what are the waste products of cellular respiration

Answer 8

carbon dioxide and water

Question 9

chlorophyll a and b

Answer 9

chlorophyll a - main photosynthetic pigment in some cyanobacteria and in plants
chlorophyll b - are accessory pigments that are important in plants but not involved directly

Question 10

chloroplasts

Answer 10

reside within plant cells and serve as the organelle of photosynthesis

Question 11

stomata

Answer 11

a chloroplast that consists fo a double membrane that surrounds a semi fluid matrix, or small opening

Question 12

equation for photosynthesis

Answer 12

6CO2 + 6H2O –> C6H12O6 + 6O2

Question 13

equation for cellular respiration

Answer 13

C6H12O6 + 6O2 –> 6CO2 + 6H2O

Question 14

where is the spongey mesophyll located

Answer 14

layer made up of loosely packed cells

Question 15

what is the function of guard cells

Answer 15

the openings of a stroma are regulated by the guard membranes
